Some special materials are solid at room temperature and require a certain temperature to maintain a molten state, such as hot melt adhesives. The physical state of hot melt adhesives changes with the change of temperature. During the coating process, it needs to pass Heat to melt the hot melt adhesive to continue coating.
The following video introduces the operation demonstration video of the hot melt adhesive melted at 120°C on the film coating machine . You can see the gradual melting process of the hot melt adhesive and the coating effect, providing a reference for users of small coating machines. Pay attention to the details of the engineer's operation while watching the video.
Note: The general heating temperature of the laboratory coating machine is within 200°C, and the heating temperature should not be set too high. If the temperature is too high, the aluminum plate may be deformed.
Below are some test demo screens of the experiment.
